Panobinostat, as known as LBH589, is a novel and potent hydroxamic acid-based deacetylase inhibitor (DACis)that inhibits a broad spectrum of histone deacetylases (HDACs), including all Classes 1, 2 and 4 HDAC enzymes, at low nanomolar concentrations. According to previous studies, it not only induces apoptosis in multiple myeloma (MM) cells via caspase activation and poly(ADP-ribose) polymerase (PARP) cleavage, but also induces potent cell growth inhibition, cell-cycle arrest, and apoptosis in a time- and dose-dependent manner in both Philadelphia chromosome-negative (Ph-) actue lymphoblastic leukemia (ALL) cells lines (T-cell MOLT-4 and pre-B-cell Reh), which are correlated with induction of histone (H3K9 and H4K8) hyperacetylation, activation of p21 and p27, and suppression of c-Myc.

| Cell experiment [1]: | |
|
Cell lines |
MCF-7aro, LTEDaro, Exe-R, Let-R, Ana-R cell lins |
|
Preparation method |
The solubility of this compound in DMSO is <10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
6d; 20 nM |
|
Applications |
To study cellular response to AIs and the mechanisms of acquired AI resistance, we used the previously generated AI-responsive cell line MCF-7aro and AI-resistant variants of MCF-7aro created following in vitro selection against each AI (i.e., Exe-R, Let-R, and Ana-R) or long-term culture in the absence of estrogen (i.e., LTEDaro). MCF-7aro, LTEDaro and three AI-resistant cell lines were exposed to increasing concentrations of LBH589. This drug-inhibited proliferation of all cell lines in a dose-dependent manner. |
| Animal experiment [1]: | |
|
Animal models |
Female, 6- to 7-week-old ovariectomized, BALB/c Nu–Nu athymic mice |
|
Dosage form |
20 mg/kg, three times per week, intraperitoneal injection |
|
Applications |
To evaluate the inhibitory effects of LBH589 on AI resistance in vivo, we used the exemestane-resistant MCF7aro xenograft model. LBH589 treatment significantly inhibited the growth of exemestane-resistant tumors; tumor weight at the end of experiment was significantly lesser in mice treated with LBH589 than in control mice. No mice in the LBH589 treat-ment groups showed significant body weight loss indicating that the LBH589 treatment was well tolerated. Consistent with the effect of LBH589 on gross character-istics of the tumors, proliferation (assessed by Ki-67 staining) of tumor cells was significantly decreased in LBH589-treated mice and apoptosis (assessed by staining for cleaved PARP) of tumor cells was significantly increased. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
